Unlike most later computers, ENIAC performed its arithmetic internally in which number system?
सही उत्तर: क) Decimal
ENIAC stored and processed numbers as decimal digits using ten-position ring counters; binary became standard with later stored-program machines.

-
RAID 6 differs from RAID 5 in that it:
सही उत्तर: क) stores two independent parity blocks and can survive the failure of two disks
RAID 6 uses double distributed parity, so any two drives can fail without data loss; it needs at least four disks.

Unlike a hard disk, which records data on concentric tracks, a CD records its data along:
सही उत्तर: ग) a single continuous spiral track
A CD has one spiral track that starts near the centre and winds outward.

-
Zone bit recording on hard disks means that:
सही उत्तर: ग) outer tracks hold more sectors than inner tracks
Outer tracks are longer, so dividing the disk into zones lets outer tracks carry more sectors and increases capacity.

-
In a hard disk drive, the platters are mounted on and rotated by the:
सही उत्तर: घ) spindle motor
The spindle motor spins all platters together at a constant speed such as 5400 or 7200 rpm.

-
Which type of flash memory, offering high density at low cost, is mainly used for mass storage in SSDs, memory cards and USB drives?
सही उत्तर: ग) NAND flash
NAND flash packs cells densely and is ideal for block storage, while NOR flash is used where fast random reads of code are needed.

Memory interleaving improves memory performance by:
सही उत्तर: घ) placing consecutive addresses in different memory banks so they can be accessed in overlapping fashion
With interleaving, while one bank is completing an access, the next bank can start, raising effective bandwidth.
